Description

[Detailed description of the invention] [Industrial application field] This invention relates to a wood peeling machine, and more specifically, it is a wood peeling machine used for stripping construction wood and in the process of manufacturing wood chips. It is related to.

[Conventional technology]

When using wood as a construction material or manufacturing wood chips, a peeling machine called a drum barker, which has a large can-shaped rotating drum with a number of peeling blades protruding from it, is used as a pre-process.

However, in order to debark a large amount of wood at the same time in a drum barker, the diameter of the drum has to be large, and the machine frame and rotation mechanism that support and rotate the drum have also become large. Since they are rotated at the same time, there is a problem of high noise and vibration, which poses pollution problems, and high equipment and power costs.

In order to eliminate these drawbacks, the special public
As described in Publication No. 46282, a hopper has a vertically erected receiving side plate and an inclined feeding side plate each having a substantially V-shaped cross section, and an opening provided along the longitudinal direction at the lower end. and a peeling rotor with a number of peeling blades protruding from the outer periphery and a peeling rotor whose upper part is inserted so as to close the lower end opening of the hopper, and allows the wood put into the hopper to fall down on the feed side plate by its own weight. The wood is scraped up by the rotation of the peeling rotary body, and the bark is removed by the peeling blade while rotating inside the hopper.The stripped wood is thrown into the hopper and removed from the shutter by opening the shutter attached to the end of the hopper. There's something to take out.

[Problem that the invention attempts to solve]

However, in the above-mentioned peeling machine, the receiving side plate and the feeding side plate are fixed, and since the hopper is removed from the shutter by opening the shutter provided at one end of the hopper, it is difficult to remove the hopper smoothly if there is a bent piece of wood, and it takes a long time to remove all the hoppers. The disadvantage is that it takes time.

This invention solves the above-mentioned drawbacks and allows one of the side plates forming the hopper to fall outward with the peeling rotor side as the center, thereby making it easier to take out the wood after it has been peeled by using the side plate as a shooter. The purpose is to

[Means for solving problems]

The above purpose is to erect a pair of supports 3a and 3b on a base 1 with frames 2a and 2b, and between these support supports, a peeling rotor 5 having a large number of peeling blades 6 protruding from its outer periphery is supported horizontally. A fixed side plate 11 is attached to one of the columns 3b erected on both sides of the peeling rotor 5, a fixed side plate 10 is attached above the other column 3a, and a bearing 17 is attached to the one frame 2a.
, one end is attached to the bearing 17, and the hopper 9 is formed together with the fixed side plates 10 and 11, and the fluid pressure actuator 18 attached to the base 1 is used to rotate and overturn the wood outwardly to take out the wood a from the hopper 9. This is achieved by providing a movable side plate 13 which acts as a shutter.

[Effect]

The wood peeling machine of this invention uses an actuator to bring the end of the movable side plate into contact with the lower end of one fixed side plate to form a hopper on the peeling rotor with the other fixed side plate, and to attach the end of the movable side plate to the lower end of one of the fixed side plates to form a hopper on the peeling rotor. Logs are loaded into the hopper from a horizontally installed live deck for transporting logs, the prime mover that rotates the rotor axis is activated, and the peeling blade of the peeling rotor peels the bark of the wood. When the peeling is completed, the actuator is activated. Then, the movable side plate is turned outward around its axis to form a shooter, and the stripped wood is rolled on the movable side plate and discharged outside through an opening opened at the bottom of the fixed side plate. . Once this ejection is complete, the movable side plate is returned to its original position to form a hopper and the next piece of wood can be stripped.

〔Example〕

As shown in Figs. 1 to 3 a and b, the wood peeling machine of this invention has mounts 2a and 2b mounted on a base 1 made of concrete. A pair of supports 3a, 3b are erected in the frame 4, and a frame 4 is installed between the frames 2a, 2b.
A peeling rotor 5 having a number of peeling blades 6 protruding from its outer periphery is mounted horizontally on the underframe 4 and is rotatable about a pivot 8 on a pair of bearings 7a and 7b mounted on the underframe 4. It is installed horizontally. One fixed side plate 10 forming a hopper 9 is provided above the one pillar 3a side, and the lower end is curved inward on the other pillar 3b side, and a tooth-shaped groove is provided on the edge through which the skinning blade 6 described above passes. 12
Attach the other fixed side plate 11 with a fixed side plate 11 formed thereon, one end of which is pivotally connected to the bearing 17 mounted on the pedestal 2a with a shaft 16, and one end of which is attached to the base 1 on the other end side of the bearing pedestal 19.
The actuator 18 is attached with one end of a fluid pressure actuator 18 that is swingably attached via the actuator 18.
A movable side plate 13 whose other end is attached with a shaft 15 between reinforcing ribs 14 is attached. On both sides of the peeling rotor 5, a pair of side plates 21a and 21b are attached to the frames 2a and 2b, forming a shutter 20 for preventing the peeled wood bark from scattering.
At the upper end of the side plate 21a, there is a guide plate 22 having a tooth-shaped groove 23 formed on the edge thereof, through which the skinning blade 6 described above passes.
is installed.

Furthermore, a gear 24 is attached to one end of the pivot 8 as shown in FIGS. 1, 2a, and 3b.
Reducer 2 directly connected to motor 25 installed above
8 is applied so that the peeling rotor 5 can be rotated at a low speed.

The wood debarking machine of this invention is constructed as described above, and the wood debarking operation will be explained below.

The movable side plate 13 operates the fluid pressure actuator 18 as shown in FIGS. After starting up and rotating the peeling rotor 5, the fixed side plates 10, 1
1 and a movable side plate 13, a certain amount of wood a is carried into the hopper 9 via a wood carrying means such as a live deck (not shown). In the hopper 9, as shown in FIG. 2b, the wood a is pushed up from the movable side plate 13 side to the fixed side plate 11 side while scraping the skin with the skinning blade 6 as the skinning rotor 5 rotates clockwise. The skin is peeled off by rotating and revolving a, and the peeled skin falls to the base 1 side via the shutter 20 formed by the side plates 21a and 21b.

When the wood bark is removed, the hydraulic actuator 1
